Choosing the wrong medicine is worse than no treatment.
Antibiotics aren't a cure-all. Wrong strain, dose, or timing not only fails to heal but causes resistance, liver damage, and wasted money. Than Vuong GMP-WHO veterinary medicines are categorized by function — choose the right medicine for the right disease.
Antibiotics aren't a cure-all — wrong strain or dose not only fails but causes resistance. Than Vuong GMP-WHO medicines: OXYTETRA (shrimp Vibrio), FLOR-MAX (Edwardsiella in pangasius), AQUA PRAZI (parasites), TETRA-C (antibiotic + vitamin C). Always identify the disease before using medicine.

- Parasites
Signs
- white feces, luminescence, hepatopancreas necrosis in shrimp. Use OXYTETRA or TETRA-C per label
- intestinal infection caused by Edwardsiella ictaluri: use FLOR-MAX; intestinal haemorrhage caused by Aeromonas and Pseudomonas: use OXYTETRA or TETRA-C
- flukes and fish lice in fish; parasites in the shrimp hepatopancreas and gut. Use AQUA PRAZI at the label dose
Solutions
- Identify disease first
- Choose right medicine: OXYTETRA (shrimp Vibrio), FLOR-MAX (Edwardsiella in pangasius), TETRA-C (antibiotic + vitamin C), AQUA PRAZI (parasites)
- Use correct dose and duration

Identify disease first — microscope or observe symptoms: white feces? Ulcers? Twisted gut? Luminescence?
Use correct dose and duration — don't stop mid-course, don't increase dose on your own
After treatment: treat environment (disinfect water, apply probiotics) + restore gut (PRO GUT, HERB GUARD)
Expected Results
Acute symptoms reduce, shrimp stabilize
Clear improvement, shrimp resume eating
Full recovery, maintain with regular probiotics

Which antibiotic to use for shrimp with Vibrio?
OXYTETRA (Oxytetracycline) is first-line for shrimp Vibrio. FLOR-MAX (Florfenicol) is registered only for pangasius (intestinal infection caused by Edwardsiella ictaluri) — not for shrimp. Identify Vibrio type before choosing medicine.
Should probiotics be stopped when using antibiotics?
Yes. Antibiotics kill beneficial microbes too. Stop probiotics during antibiotic course, resume SOILMAX New + PRO GUT for gut recovery after 5-7 day course.
What parasites does AQUA PRAZI treat?
Per label: in fish — monogenean flukes, fish lice, liver flukes, tapeworms (100 g per 20–30 kg feed, 3–5 days); in shrimp — parasites in the hepatopancreas and gut (prevention 1–2 g/kg feed for 2–3 days; treatment 3–5 g/kg feed, 1–2 times a day for 3–4 days). Stop 4 weeks before harvest.
Are Than Vuong veterinary medicines GMP-WHO certified?
Yes. All Than Vuong veterinary medicines are manufactured in a GMP-WHO certified facility, ensuring consistent quality and accurate active ingredient content per registration.
What is antibiotic resistance and how to prevent it?
Resistance occurs when bacteria mutate to withstand antibiotics. Prevention: (1) don't use antibiotics preventively, (2) correct dose + full course, (3) prioritize probiotics and herbals for mild cases.
